A guide to software-defined storage

This ComputerWeekly.com guide gives you the lowdown on software-defined storage: What is it, what it isn’t, what it can do for you, and how suppliers’ implementations differ.

Driven by server virtualisation in the datacentre, the IT world has gone software-defined crazy. Compute, networks and now storage have all been hitched to the software-defined wagon. But what is software-defined storage and what can it do for you?

The software-defined storage scene is a mix of storage virtualisation technologies that have been around for years and newer iterations, in particular from giants such as EMC/VMware that merge software-managed pools of virtualised storage with big data and hyperscale capabilities.

So, how can software-defined storage work for you? This ComputerWeekly.com guide walks you through all the key decision points of software-defined storage.
